PUELH'TGJACK" non MOTOR-VEHICLES;

certain new and useful Pulling-Jack 01 MotorrVehicles, of which the following is a specification.

My 'nvention relates to pullingjacks for motor vehicle's'of the type adapted to be detachably mounted on, traction wheels theredrum on which may be wound. a rope or; chain secured to .a; post stake or other stationary obj ect, whereby the motor car may be drawn .out of a mud hole orthelikebyits own power;

A further object isto prov de a device of the. kind mentioned comprising a drum with 'means'for quickly and easily attaching the. drum to the wheel of a motor vehicle.

A-further object" is to provide such a devicewhichcan'be quickly and easily assembled or taken apart and packed in a com paratively small space.

Still a, further objectis to provide such a" device capable of being made up, of detachable parts, the. device being. so constructed and arranged that most of the parts may be made in standard sizes and by slightly chan ingthe size of two parts, the device may e adjusted for use on car wheels of various sizes.

My invention consists in the construction, arrangement and combination of the various parts ofthe device whereby the objects contemplated are attained as hereinaftermore ings, in which:

portion of a motor car equipped with a pulling-jack embodying invention.

'Fig; 2 shows a vertical, sectional view taken' on; the line 22 of Fig. 1. ge Y 3 section and partly broken-away of the commy device,'and Fig; l shows aperspective view of one of the arms for connecting the drums to the wheel.

In the illustration of myinvention, which is shown in the accompanying drawings, 1 have shown my improved device mounted on the rear wheel of an ordinary automobile andhave used the reference numeral-'10 toindicate the automobile andthe referencenumeral 11 to indicate the spokes 12 andthe rim 13.- I

It will be understoodthat one of my devices including the drum thereof is designed to be mounted=oneach rearwheel of a motorvehicle andthe ropes or chain s or the the wheel, which has like. are secured'to some stationary object either in front or in the rear of the ve-' hicle, and are thenwound 'on the drum. 1

My improved pulling jaclrin each case comprises a drum .lihavin-g the 'form of a hollow tubular portion.

The-drum- 14 may be made of a piece of sheet metal bent in hexagonal form. 1 The drum.-1 l atone end thereof is provided on each of its siX sides with an out-, wardly extending flange 15, which is preferabl y inclined away from the drum at an obtuse angle withr'elation thereto. Y

Theouter endsof the fianges 15 are pref-- erably/ connected "and reinforced by. means ofan annular ring .16 which is secured to all of the flanges 15.

At the other end of tlredrum 14:, opposite each flange15,;is a shorter flange 17 'eX- tendingradially away from the drum 14. Each flange 15 adjacent to the drum 1,4 is- -provided with an angular open1ng18. Each flange 17 is provided with an opening19, preferably round arranged in line with the opening 18 of the opposite flange 15.

The flanges 15 together with the annular member 16 form a retainingdevice for a rope or the like wound on the drum.:

For securingthe drum to the wheel ofa motor vehicle I have provided a series of arms each comprisinga horizontal. portion 20 angular in crosssection and designed lit. the openings 18 and having-.- shorter smaller round extensions 21 designed to 19v and provided with 22 at their ends.

Formed on each member 20 is an extension arm 23 extending from the end of the screw-threads a connection with stakes member opposite the portion 21 and inclined away therefrom at an obtuse angle with relation thereto.

The free end of the extension arm 23 is split and formed into two parts, one of which 24 is bent to a spiral shape and'is adapted to be fitted around the spoke 12 .of a Wheel. the extension arm 23 is'in'clinedaWay from the portion 23 at 25 and is adapted-toengage one side 1 and;2. H

In assembling my improved derstood that there are as many securing arms 20 as the drum has sides. 'In the form of the device herein illustrated, the drum being hexagonal, there are six of the securing arms.

The extended through the angular openings 18 in the flanges l5 and rest adjacent to the drum sides extending across the drumyfrom end to end with the portions 21 received in the openings 19' inthe flanges 17.

Arranged against the end of the drum 14: having the flanges 17 is an annular disk 26 having suitable openings receiving the por tions 21, as shown in Fig. 2, and held in position by nuts 27 on the portions 21.

The disk 26 has an outwardly flaring flange 28 which serves as a'retaining device for the rope or the like 29.

taining arms are preferably placed on the spokes first and the members 20 then inserted through the openings in the flanges of the drums.

When the device has been assembled as hereinbefore described, it will be seen that the drum is rigidly mounted on the wheel, and rigidly supported with relation thereto and is spaced away from thewheel, so that therope or the like 29 will not be interfered with by the running board when itsforward end isfastened to a stake or the like.-

It will be noted that the drum is reinforced and braced by the securing arms and also that the annular member 16 serves to reinforce and strengthen the drum.

The disk 26 also serves to strengthen the drum and make it rigid.

My improved device is preferably used in and ropes or the like and preferably arranged substantially, as shown in my application for patent filed March 7 1916, Serial Number 82,623.

The rope 29 has a hook 30 whichcan be secured over one of the flanges l5 and one or two windings of the rope may be madeon the drum. One ofthe drums having been secured to each hind wheel of the motor vehicle and the ropes secured'at proper points,

The other part of the split end of of a spoke, as shown in Figs,

Pu r d? and installing it on the car-,"it will-be-unof v the. working provided with at the other endbeing provided with round I of arms each having a,

be secured to awheel In mounting the deviceon a wheel, the respoke, a;

tool, except a wrench, and when taken apart can be stored in comparatively small space 'inthe tool box or the like.

It does not in any way interfere with any mounted farenough away from the wheel, so that the car will not bemarred or dis figured by the flexible device 29. portions 20 of "the securing arms are Some changesmay' be made in the construction and arrangement of'the parts of my improved pullingjack, withoutfdepartingfrom its essential features and purposes, and it is my intention to cover bythis application, any such changes which may be in cludedwithinjthescope of my claims I claim as my invention:

1. Ina device "of the class "described, a drum having at its periphery at its opposite ends flanges, the flanges beingarrangedin opposite pairs, the flanges-at one end being angular openings, the flanges openings, a plurality portion adaptedto portion designed to extend away from the spoke and toward the line of the extended axis of the wheel, a portion angular in cross section extended through one of the angular openings in said'flanges', and a reduced cylindrical portion on one end extended through one of said round openings, and locking of said last described portions.

2. In a device of the'class described, .a hexagonal drum having a pair of'outwardly extending flanges on each sidefthe members of each pair being arranged at opposite ends of the drum, the'members of eachv pair being provided. with openings arranged close to the body of the drum, means for connect ing and reinforcing the flanges on oneend of the drum, said means and the flanges at parts ofithecar andis' and away from the wheel and and a portion extended through the openings of one pairoffla'n'ges;

the openings in he flanges of one end ofthe drum and the portion of the arms received therein being irregular in outline to prevent turning of said arms in said last mentioned. opening, the last described portions of said arms being arranged to rest adjacent to the respective sides of the drum, an annular member arranged adjacent to the end of the drum opposite that having the connected flanges, provided with a plurality of openings receiving the free ends of said arms, and fastening means on the free ends of said arms.
